OIL-BURNER.

Specification of Letters Patent.

Application filed October 7, 1919. Serial No. 329,075.

To aZZ whom '5t may cof/wem:

Be it known that we, WILLIAM T. HUR- LEY and ELMER L. ENGLE, bothcitizens of the United States, residing at Sacramento, in the county ofSacramento and State of California, have invented new and usefulImprovements in Oil-Burners, of which the following is a specification.

.This invention relates to heat generating means and particularlyrelates to an oil burner.

It is the principal object of the present invention to provide simplemeans whereby a hydro-carbon fuel may be delivered to a burner in aliquid condition and there vaporize for the purposes of combustion, atthe same time insuring that the combustion of the fuel will act upon theliquid fuel to sustain the vapor-ization continuously.

The present' invention contemplates the use lof a burner adapted to beregulated by any suitable valve means and which is in communication witha raporizing dome disposed thereover, said dome being supplied withliquid fuel from any source of supply and said fuel being convertedwithin said dome to a gas which thereafter passes through the burner asregulated by a Valve.

The invention is illustrated by way of example in the accompanyingdrawings, in which- Figure 1 is a view in side elevation, showing thecomplete burner.

Fig. 2 is a view in vertical section through the burner, more clearlyillustrating the details of its construction.

In the drawings, 10 indicates a supply pipe through which liquidhydro-carbon fuel is delivered. This pipe is fitted with a regulatingvalve 11 for controlling the flow of the fuel to a vaporizing dome 12.The dome is here shown as hemispherical and with its equatorial portionin a horizontal position. This dome may be supported in any desiredmanner but is shown in the present instance as fitted with a pluralityof bosses 13, to which legs 14 are;vv

fastened. Extending upwardly from the hemispherical shell 15 of the dome1s a tubular projection 16. This portion is substantially cylindricaland its interioris in communication with the interior of the dome.Extending through the interior of the dome and projecting a considerabledistance upwardly within the extension 16 is a vertically disposed gaspipe 17 This pipe ,tubular extension 16 of the dome.

is threaded through a boss 18 formed in the base portion 19 of the domestructure. The boss 18 is in communication with a valve casing 20,beneath the dome, and within which a suitable valve mechanism may behoused such as the needle valve 21, which may be regulated by hand wheel22. The needle valve will control the flow of gaseous fuel from the pipe17 to a burner nozzle 23. This nozzle is here shown as formed with anelbow which permits its opened end 24: to be beneath the base portionl19of the dome and substantially in vertical alinement with the centralaxis thereof. In this manner the base portion 19 of the dome will act asa damper plate and will receive the heat fromthe fuel which is burningand the flames which are impigning against the underface of the dome.

Suspended beneath the vertically extending portion of the fuel nozzle 23is a drip pan 25 within which an accumulation of liquid fuel may takeplace and by which ignition of the fuel passing from the nozzle 24 maybe initially'made. y

In the `operation of the present invention it will be understood that adesired quantity of liquid fuel may be placed in the pan 25 and thatthis may be ignited; at the same time allowing the needle valve 21 to beopened. When the fuel in thedrip pan is ignited, it will cause a flameto flare up and surround the nozzle` 23 and possibly strike against theunderface of the basek wall 19 of the dome. As fuel is delivered throughthe nozzle, this will also be ignited andthe performance of the burnerstarted. The heat of the flame passing upwardly from the nozzle 23 willbe imparted to the dome 12 as this flame impinges against the underfaceof the dome and will act to heat the accumulated quantity of liquid fuelwithin the dome. This will cause volatilization of the liquid fuel whichwill again pass upwardly in the form of gas and find its way into the Asit is -forced`upwardly it will be forced downwardly through the pipe 17and through the burner. It will therefore be seen that the fuel whichhas originally been delivered to It will be evident thatlby use of thedisclosed structure a very simple and inexpensive burner is provided,which burner is ef iicient 1n its operation and insures that a maximumheat may be produced by a minimum amount of liquid fuel and that the`fiame resulting therefrom will be clean and odorless.

While we have shown the preferred form of our invention, as now known tous, it will be understood that various changes may be made in theconstruction, combination and arrangement of the parts without departingfrom the spirit of the invention as claimed. v

Having thus described our invention, what we claim and desire to secureby Letters Patent is l. An oil burner including in combination a hollowdome and supports therefor, a tubular extension extending upwardlytherefrom, a fuel supply pipe communicating with the interior of saiddome, a gaseous fuel pipe within the tubular extension and extendingdownwardly belowthe dome, said .pipe carrying on its lower end aT-connection, one end 0f which is provided with a valve to regulate theflow of. gaseous fuel therefrom, and the other end with a burner adaptedto direct Athis flame against vthe lower portion of the dome.

2. An oil burner including in combination a hollow dome and supportstherefor, a tubular extension extending upwardly therefrom, a fuelsupply pipe communicating with the interior of said dome, a gaseous fuelpipe Within the tubular extension and extending downwardly below thedome, said pipe carrying on its lower end a -T-connection, one end ofwhich is provided with a valve to regulate the flow of gaseous fueltherefrom, and the other end having an upwardly turned portion, the freeend of which is provided with a burner adapted to direct its amesagainst the lower portion of the dome. Y

3. An oil burner including in combination a hollow dome and supportstherefor, a tubular extension extending upwardly therefrom,'a fuelsupply pipe communicating with the interior of said dome, a gaseous fuelpipe within the tubular extension and extending downwardly below thedome, said pipe carrying on its lower end a T-connection, one end ofwhich is provided with a valve vto regulate the flow of gaseous fueltherefrom and the other end having an upwardly turned portion, the freeend of which is provided with a burner adapted t0 direct its fiamesagainst the lower portion of the dome, and a drip pan secured beneaththe burner.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
